To all whom may concern: I.

Be it known that I, PHILIP D. HIBNER, a citizen of the United States, residing at Seattle, in the county of King and Stateof l. .n-hington, have invented certain new and useful improvements in Means for Regulating Fuel Mixtures for lnternaLCombustion invention relates to internal combustion orig The ob ectv of the invention is the provision of improved means for forming a suitably proportioned.admixture of hydro-carbon oil and a r, and regulating the supply of this combustible to the explosion chamber of the engine for the purpose of controlling the en ,gine speed and its capacity to perform work.

The invention consists in the novel eon- StCllClJiiJll, arrangement and combination of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a view in transverse vertical section of apparatus embodying. the present invention. Fig. 2 is a view partly in plan and partly in horizontal section of the same. Fig. 3 is a transverse vertical sectional view taken through of Fig. 2 and illustrating the movable elements thereof indifierent operative positions from which they are represented in Pig. 1.

R 'ierringto said drawings, the numeral 5 designates a casing of tubular form having an oscillatory valve Whiclris constituted of two axially alined members 6 and T spaced to provides passageway 8 therebetween and extending diametrically of the valve. The valve lllell'lbui 6 consists of a body substantially as shown having parallel side faces 6 which fit against faces '7 of bifurcations 7 provided on the other member 7. The opposing walls 6" and 7 of the respective mem bers are desirably formed in parallel. relations with each other and in planes oblique to the axis of the valve.

- Ports 9 and 9 are provided at diai'netrisally opposite sides in the peripheral ivalls of the casing, and a third port 10 1s'prov1dcd in the casing above t is valve. Said ports are Engines of which the following is a specifirelatively narrow and are disposed helicelly 1n the casing so as to register with the respective ends oi the Way 8 when the valve'is suitably rotated.

The oil for the explosive mixture is fed into the valve-Way by means of a pipe ll extending from. an oil reservoir 12 to the port 10. ducted by a pipe 13 extending from a source of air supply to the port 9, whence it is de livercd with the oil through the port 9 and the communicating pipe 14: when the valveway is brought into register with theports The air for such mixture is con- 9 and 9 The air and oil composing the can" plosive agent may be drawn through the delivery. pipe 1i by the suction or vacuum generated 1n the operation of the engine, but

preferably the oil is forced from the valveway and through said delivery pipe by a jet of air supplied under considerable pressure to the pipe 13 whereby the oil is more thoroughly vaporized and combined with the-air.

lVhcre compressed-air is thus used, a vent hole 15 is provided in the casing intermediate ports 9 and 10 for the escape of superfluous air from the valve-way and from. which it is led by a pipe'15 to the reservoir 12. The quantity of air supplied for each charge is regulated by means of a valve indi-' cated by 16 in the pipe 13 and the amount of oil may be determined by adjusting the relative positions of the valve members (3 and 7 to correspondingly vary the size of the Way 8.

To these ends, the valve member 7 is so cured against end motion and the memberl; moved axially in the casing, as by mcansof a bell-crank lever 17 which is actuated to shift the memberthrough the agency oi stem 18. The latter may be connected to the lever by means of a collar 10 engaging in peripheral groove oi the stern and by means of studs,

such as 19 engaging in slots royidcd in the forked end i7 of the lever.

20 represents a nut carried by the lever arm 17 and engageablc with a screw 21 which is utilized to influence the lever for adjustably moving the valve part 6.

22 represents a stuiiing box provided in the casing and 5 to prevent leakage of air about the stem from the casing chamber 23 through which said stem cXtends. 24: is a duct tor the passage of air from pipe 13 to said cham her.

In operation, the valve is oscillated about its axis to present the passageway successively to the aforesaid oil and air pipes for each of the successive cycles in which the engine is supplied with a charge of combustible; for which purpose the valve is provided exteriorly of the :asing with an arm can rying a crank-pin 26 extending into a slot 27 provided in the end of a rod 28 which is rcciprocated by an eccentric (not shown) driven from the engine shaft or otherwise.

The slot 27 of said rod is made somewhat longer than the diameter of the pin. 26 to atford, upon occasion, movement to the rod in.- depcndently of the motion which is imparted to the crank-arm through the agency of the eccentric rod.

To regulate such relative movements oi the rod and crank-arm, I provide in. the former adjustable stops in the nature of screws 29 and L) which may be advanced or retracted to lessen or increase the effective space therebetwccn and likewise regulate the positions at which the'pin 26 will be cncountered by the respective stops during the reciprocatory travel ot the same.

The operation of the invention may he explained as follows:

When the valve (3---T is in the position in which it is represented in F g. l, the oil from the reservoir flows into the way 8 until the latter is filled or until the valve is rotated in the direction ind. :ted by the arrow in Fig. l. to cause such way to be moved out of communication with the port ll). This move ment of the valve is cli'cctcd through the mellllllll of the rod 2% and by regulating the piircnc'agiug screw 2!), it is evident that more or less lost motion may ensue to the rod with atl'ccting the valve to accordingly allow the way thcreoi to remain in oilereceiving position during the initial portion o1 the return stroke of the rod.

The continued travel of the rod rotates the valve into the position in which it is represented in Fig. 3 to connect the two ports 9 and 9 whereupon the air supplied under pressure by pipe 13 will serve to eject the charge of oil therefrom to escape as a combustible mixture through delivery pipe l t to the eXplosion chamber of the engine with which my devices are employed.

The way 8 may be caused to remain for a determinable period of time in its Fig. 3 position by adjusting the screw 29 (Figs. 1 and 2} so that the rod 28 will have lost motion with respect to the arm during the beginning of the outward stroke of the rod.

As he way 8 passes the vent hole 15 when the valve is being rotated to receive another charge of oil, communication is established between the way and the air space in the res crvoir, resulting in the flow of air, due to its relatively strong pressure, from the way into the reservoir to accelerate the outflow of oil from the same when the way subseintently arrives in position to receive the oil.

lly regulating through the offices of lever 17 and stem 18, the axial position of the valve part 6 with respectto the other part 7, the capacity of the way 8 may be selectively varied to increase or decrease the oil charges. The quantity of air supplied through pipe 13 may also be controlled by means of the valve 16,
